切，中国城市 下水道狭小 街道被淹 又不是 一天二天了，最起码 从我记事起 有 40年了。全国各地城市被淹 时有所闻
去年 今年 更是了，铺天盖地的 各地城市被淹的消息。 死人无数。
你中共 不吹牛还好，你要吹牛 就是各种打脸
给你说是容量问题，舍得花钱可以扩容，没钱或者不值得的话有必要扩容吗？
看看美国这些城市，被水淹的频率越来越高，都没扩容，电力中断也很频繁，也没改进，也不能说美国吹牛对吧？就是值当不值当有没有钱改进的问题。
Key Points
Flooding is becoming more frequent along much of the U.S. coastline. Most sites measured have experienced an increase in coastal flooding since the 1950s (see Figure 1).
Over the last decade (i.e., since 2014), Ketchikan, Alaska, has exceeded the flood threshold most often—an average of 31.7 days per year—followed by Hilo, Hawai‘i, and Galveston, Texas (see Figure 1). At more than half of the locations shown, floods are now at least five times more common than they were in the 1950s.
The average number of flood events per year has progressively accelerated across decades since 1950. The rate of increase of flood events per year is the largest at most locations in Hawai‘i and along the East and Gulf Coasts (see Figure 2).
Flooding has increased less dramatically in places where relative sea level has not risen as quickly as it has elsewhere in the United States (as shown by the Sea Level indicator). Five sites in Alaska and along the West Coast have experienced a decrease in coastal flooding (Figures 1 and 2), coinciding with decreasing relative sea level as the land itself is rising.
